In
the first study of its kind, William Marras (right), director of the Biodynamics
Laboratory at Ohio State, and his colleagues developed a mathematical
technique to gauge the muscle exertions of people with back injuries.
Here, a volunteer (left) in the Biodynamics Laboratory wears the Lumbar
Motion Monitor, a device Marras invented in the early 1990s to electronically
monitor back movements. High-resolution version of this image available
